If you're a vehicle possessor and happen to accept a motorcar blow in the near future (nosotros hope you lot don't), it's likely the crash details will be recorded. Automotive "black boxes" are now congenital into more than 90 percent of new cars, and the regime is because making them mandatory.

Dave Wells, a detective at the King County Sheriff's Part in Washington state, specializes in accident reconstruction. That ways he'southward often crouched under steering wheels, looking for the connector that mechanics employ to become diagnostic codes. Simply Wells is using a different kind of tool, and information technology pulls out a very different kind of information.

Reading a sampling off his laptop, he says, "In the offset 10 milliseconds they're up to a one-half-mile-per-hour acceleration."

This is crash data — moment-past-moment statistics saved from the car's near recent collision. There'southward speed, acceleration, braking — even information from within the motorcar.

"At that place are sensors under your seat," he explains. "So if someone tried to say in that location was another person in the car at a crash who had run abroad, this shows at the fourth dimension of collision there was not."

The Black Box In Court

Put information technology all together, and you become a detailed picture of the seconds right before and afterward a crash. The information comes from something called an "event data recorder"; the EDR has get primal to insurance investigations, lawsuits and even criminal cases. Merely that wasn't its original purpose.

"Information technology was never designed for investigative purposes," Wells says. "It was designed for ... motor vehicle safety and keeping people less injured and alive."

EDRs are part of a car's safety arrangement, which has to make divide-2nd decisions, for example, whether to pull seat belts tighter or inflate the airbags. And engineers like to see data from real-earth crashes to track how those systems are working. And so the EDRs save the crash data, and equally rubber systems grow more circuitous, the recorders continue saving more than data.

"I don't think you lot'll find very many Americans who know these devices are in their cars," says Rep. Michael Capuano, D-Mass. For eight years now, he has been trying to pass legislation giving drivers the correct to opt out.

The Option To Turn It Off

"I would fence that this is a device that the average person should exist able to turn off if they so desire," he says. "Obviously, if that were an option, some insurance companies might want to have that into consideration in pricing insurance; I understand that. But nonetheless, I think the average person should have that choice."

EDRs have been around for a while, but the issue is surfacing again because the National Highway Traffic Safety Assistants has proposed making the devices mandatory on all new cars, starting next year. That's defenseless the attention of privacy experts like Nate Cardozo, a staff chaser with the Electronic Frontier Foundation.

"The corporeality of data that they record is vast. And information technology's not capped," Cardozo says. "And I found that to exist quite problematic."

Cardozo sees the safety value of the crash data, but he says information technology'south important to set limits — particularly every bit cars' digital storage capacity grows. He besides says the feds should clarify who gets the data.

A Grey Area

Some states restrict what insurance companies tin exercise with EDR data and require police to get a warrant before plugging in. Only in much of the country, information technology'southward still a gray area.

"They could do something like put a notification in the owner's manual saying that the driver has a reasonable expectation of privacy in that black box data. We recall that would go a long fashion towards making the issue of who owns that data a lot more clear," Cardozo says.

NHTSA won't discuss its plans — because it'due south in the procedure of writing the proposed new rule making the recorders mandatory — but in the past, some NHSTA officials accept suggested the privacy of crash data as an consequence that should be taken up past Congress.

In King County, Wells says he doesn't think the saved crash data should scare people.

"Generally, the information from this is going to assist them in an accident," he says. "It'southward at least going to point out ane thing, and that's the facts."

Wells says privacy-conscious drivers should worry more nearly GPS and built-in services that offer roadside assistance. The departure is, on new cars, those systems will notwithstanding be an option.
